2. 1D Motion / Kinematics

A police car at rest is passed by a speeder traveling at a constant 140 km/h. The police officer takes off in hot pursuit and catches up to the speeder in 850 m, maintaining a constant acceleration.

(a) Qualitatively plot the position vs. time graph for both cars from the police car's start to the catch-up point.

Calculate (b) how long it took the police officer to overtake the speeder,

A police car at rest is passed by a speeder traveling at a constant 140 km/h. The police officer takes off in hot pursuit and catches up to the speeder in 850 m, maintaining a constant acceleration. Qualitatively plot the position vs. time graph for both cars from the police car's start to the catch-up point.

Draw position, velocity, and acceleration graphs for the ball shown in FIGURE P2.44. See Problem 43 for more information.

Sketch the v vs. t graph for the object whose displacement as a function of time is given by Fig. 2–40.
